SPECIFICATION forming part of Letters Patent No. 418,052, dated December24, 1889.

Application filed September 25, 1889. Serial No. 325,000. (No model.)

To aZZ whom it may concern.-

Be it known that we, WILLIAM PARTRIDGE and WILLIAM JAMEs McGUToIIEo Jr., of Allegheny, in the county of Allegheny and State of Pennsylvania,have invented certain new and useful Improvements in'MetallicRailway-Ties; and we do hereby declare the following to be a full,clear, and exact description of theinvention, such as will enable othersskilled in the art to which it pertains to make and use it referencebeing had to the accompanying drawings, which form part of thisspecification.

Our invention relates to an improvement in railway-ties; and it consistsin a metallic tie which is given a triangular shape, in combination witha metallic brace which is placed inside of the tie, in the manner andfor the purpose hereinafter set forth and claimed.

It also consists in the arrangement and combination of parts which willbe more fully described hereinafter.

The objectof our invention is to produce a railroad-tie which is madefrom metal of any desired thickness, and which is more durable andelastic than the wooden ties now in use.

Figure 1 is a longitudinal section of a tie which embodies ourinvention. Fig. 2 is a vertical section of the same taken at rightangles to Fig. 1. Figs. 3 and I are detail views.

A represents the tie, which is made of metal of any desired thickness orkind, and which is rolled, bent, or given a triangular shape in anymanner that may be preferred. In order to brace and strengthen the tie,there is placed inside' of it, under the rails, where the chairs aresecured in position, suitable metallic braces 13,01: any suitableconstruction, and which form an additional thickness of metal at thatpoint where the chair is to be secured. Either the lower ends of thesebraces may project through the opening at the lower edge of the tie andbe bent up along opposite sides, as shown in Figs. 1 and 2, or the lowerportion of the tie may be closed by an angular plate I, as shown in Fiat, which will cover the lower edge of the tie and extend upward uponopposite sides any desired distance. These braces may be fastened inposition by means of bolts or any other suitable devices that may bepreferred. The top of the tie forms a broad base or bearing for thechairs and the rails, while the sharp portion of the tie projects downin the ballast. This triangular shape of the tie causes it to packsolidly in the ground, and at the same time enables it to be quicklyraised and easily moved when it becomes necessary to do so.

Each end of the tie will be filled by a triangular block of wood a,which will extend into the tie far enough to be held securely inposition by the bolt Q, or fastening which holds a portion of the chairin position. After the tie has been completed, but before the block isinserted, it is dipped in hot tar or pitch, so as to thoroughly coatevery part and protect it from rust. The blocks of wood a, before theyare inserted in the ends, are also dipped in tar, so as to preserve themfrom decay.

Near each end of the tie and through the bracesB,placed therein,arepunched or formed in any suitable manner bolt-holes, through whichclampingbolts are passed for the pur pose of securing the part D of thechair in position. This part D has one flange to ex tend up along theside of the rail, and has its lower portion made so as to receive thebottom flange of the rail, as shown; also secured to the tie by suitablebolts is the metallic block or brace I, which has its inner end bearingsolidly against the opposite side of the rail from the part D of thechair, and thus holds the rail rigidly in position.

In order to brace and strengthen the ends of the tie, a brace-plate O isapplied to each end, and this plate has an arm P, which extends alongupon the top of the tie, and is secured in position by the bolt Q, whichsecures the block I in place. This brace-plate forms a double thicknessof metal at each end of the tie, so that it will not be battered or bentout of shape during transportation.

Having thus described our invention, we claim- 1. The combination of ametallic tie and brace placed inside of the tie with the chair composedof the two parts D I, which hold the rail from opposite sides,substantially as set forth.

2. A metallic tie made triangular in crosssect-ion, whereby one of itsedges is adapted to be forced into the earth, in combination with theblocks of wood a, which close its ends, substantially as shown.

3. A metallic tie triangular in cross-section, whereby one of its edgesis adapted to be forced down into the earth, iii-combination with themetallic brace B, which is placed inside of the tie, and which has thesame shape as the tie itself, in combination with the rail,

and the chair by which the rail is secured in position, substantially asdescribed.

4. The combination of a metallic tie, the blocks a, which close itsends, and the braceplates 0, placed around the ends of the tie andprovided with the extension P, through which the bolt Q is passed,substantially as specified.

In testimony whereof We affix our signatures in presence of twowitnesses.
